All of those suggestions have never worked well for me. Even the guarantee cabin we once received turned out to be a dud.I'll stick to my selected cabin & be happy with it, knowing it size & location & not be surprised by noise in the early morning, music being played late at night or other unseen cabin problems.

We got assigned into a guaranteed room one cruise that was a room from hell. No air conditioning to speak of and there was no other cabin available to switch into. I think they well know about these problem cabins from past cruisers complaints & hold them back until they're forced to assign them. I'm positive there are loads of cabins they know are problem cabins & only use them as a last resort to fill the ship and maximize profits.(only a hunch)
